F3 and F1 boards

[EBA]

I search four F3 boards and four F1 boards for my system or a shematics board.

I also search the shematic of the F3 PSU.😕

Please a quick direction.

Best regards

Here you go! This is the F3 power supply. The secondaries will give you 36v and 50v after the bridge. That's 1 channel.
If you want to power 2 channels with one transformer, use a 36v-0/36v-0 at around 8-9 amps, 575VA or higher. F3 draws around 2.2 amps constantly.

Be sure to use 4 .47, 3w resistors in the CRC of the filter bank.

Hope this helps.

Zen Mod and Flg,

I read the differents manuals of F1,F2,F3,F4 and F5 amp's.

I anderstood, the Nelson Pass PSU is general PSU for all the circuits whith 3 optional DC tension of 46V, +- 23 V or +23 V with the same components.

And the board is avaible in the store of this forum.

I don't ask the evidence, sorry.😉

Best regards
